Specifications
Target Information
Der p 21 is a potent, low-molecular-weight allergen identified in the feces of the European house dust mite (Dermatophagoides pteronyssinus). Classified as a member of the MD-2-related lipid-recognition protein family, it shares structural homology with the LPS-binding protein MD-2. This structural mimicry allows Der p 21 to activate the TLR4 signaling pathway, triggering robust IgE-mediated Th2 immune responses. It is a major target in diagnostic assays and allergen-specific immunotherapy (AIT) for patients suffering from mite-induced asthma and allergic rhinitis.
